Webb10 dec. 2024 · 1 Answer. Sorted by: 5. model in line model = sm.OLS (y_train,X_train [:, [0,1,2,3,4,6]]), when trained that way, assumes the input data is 6-dimensional, as the 5th column of X_train is dropped. This requires the test data (in this case X_test) to be 6-dimensional too. This is why y_pred = result.predict (X_test) didn't work because X_test … Webb8 aug. 2024 · Please take a look at matrix dot product (Wikipedia), for a.b the required matrices should have size of NxM and MxN respectively.

Additionality, I changed linreg.predict(...) response shape to get single column for concatenate operation. WebbSorted by: 0 The score method of the classifier object does not work the way you are trying it to. You need to directly give x_test as input and that it will calculate y_pred on its own and give you the result with y_test. So, you do not need to reshape and the correct syntax would be: y = clf.score (x_test, y_test) Webb13 jan. 2024 · ValueError: shapes (5,1) and (10,) not aligned: 1 (dim 1) != 10 (dim 0) · Issue #126 · bd-j/prospector · GitHub bd-j / prospector Public Notifications Fork 61 Star 121 Code Issues 26 Pull requests 2 Actions Projects Wiki Security Insights New issue ValueError: shapes (5,1) and (10,) not aligned: 1 (dim 1) != 10 (dim 0) #126 Closed fishing reno
